STL System - FM Transmitter

Product Details

The STL Antenna (Studio Transmitter Link) is engineered to reliably relay audio signals from your studio location to a remote transmitter site, supporting a maximum transmission distance of up to 60 km under clear line-of-sight conditions. It is widely used by radio stations, broadcast groups, and community stations that need to separate their studio and transmitter locations while maintaining a strong, stable link.

Built with weather-resistant materials for outdoor tower or rooftop mounting, the STL antenna withstands harsh climates and long-term outdoor exposure. As part of a complete STL link setup, it works together with an STL transmitter/receiver pair and matching coaxial cable to deliver a clean, low-latency signal path. RS Radio manufactures all core components in-house, ensuring compatibility and consistent quality across your entire broadcast chain.
